This allows you to have the polyfill module monkey-patch what you want so it
is always monkey-patched. It will also do so in an intelligent way.

Version Comparison

Flake8 2.x did not include an object that would allow for easy version
comparison. Flake8 3.0, however, added a __version_info__ attribute. For
consistency, Flake8 Polyfill will turn 2.x’s version string into a tuple
suitable for comparison.
